Learning How to Convert XML to JSON, JSON to YAML and Vice Versa.


YAML is one of the languages that has gained popularity in recent times. Applications such as OpenAPI, Swagger, DevOps, and Kubernetes use YAML to create human-readable configurations at a large scale. What is the key element in such integrations? You need to write YAML code so that it can be understood easily by developers. You will be learning about YAML language constructs from scratch in this course.

In this course, you will learn about JSON, YAML, and JSONPath.

  1. In the first part, you will learn about JSON. JSON is primarily used in web development, where the data is being stored and transmitted. This is slowly replacing the XML.
  2. Once you get comfortable with it, we will move on to the second part, which is YAML. YAML is primarily used in Tools such as Ansible and Kubernetes.
  3. Finally, in part-3, you will learn about JSONPath. JSONPath is used to extract a subset of data from JSON files. This is similar to SQL for relational Databases.
